SPECIFICATIONS:

GUIDE SPECIFICATION:Tempering valve and recirculation pump shall be provided within an Acorn Command Station. Included will be combination temperature/pressure gauges on the inlets and outlet, full port lockable ball valves for service stops, cartridge-style inlet checks w/strainers, a hose connection for creating demand locally, a circuit setter (or thermostatic balancing valve), an Aquastat (optional) , a

®120V GFCI convenience outlet and a by-pass loop for ease of set-up. The entire assembly will be attached to a welded unistrut frame for support and to assist in mounting the finished assembly. The complete assembly shall be air tested for the integrity of all connections. Checkstops are not acceptable as the inlet service stops. The assembly shall be lead-free. Acorn model Number CSMV-XXXXXX. Re-Circulation pump model ____________.

FEATURES:

l Combination Temperature/Pressure gauges .

l Commercial quality thermal actuator provides repeatable, reliable performance.

l®Factory assembled to a heavy duty, welded unistrut for

quick and easy installation. Assembly is pneumatically tested as a complete unit to 80 PSI (556 kPa).

l A GFCI receptacle for electrical components.

l ™ Upgradable to Acorn BASyC (CSMV-1 is not Upgradable).

l G Lead-Free solid brass body with corrosion resistant and lead-free internal components.

l Temperature adjustment is made using an Allen wrench. A locknut on the bonnet prevents unauthorized or accidental temperature adjustment.

l The MV17 is capable of exceeding the temperature control accuracy requirements of ASSE 1017 at Zero GPM actual user demand. The system must include a continuously operating Re-Circulation pump capable of meeting the minimum flow rate shown on the included chart (.5 to 4 GPM based on the model) with a correctly adjusted balancing valve.

l Integral checks with screens to prevent backflow and to filter debris from entering the valve.

l Includes lockable brass ball valves.

l Valves are IAPMO certified per ASSE 1017 and CSA B125.3.

* Under Normal Operating Conditions.G The wetted surface of these valves contacted by consumable water contains less than 0.25% of lead by weight in conformance with national lead free law.

DESCRIPTION:The Acorn Controls Command Station is a self-contained tempering and Re-Circulating system. Every system is factory assembled to a welded heavy duty mounting frame for simplified installation. The Acorn Command Stations are 100% factory tested and utilize the MV17 valve (or valves) which are IAPMO certified, at the published minimum flow, to exceed the performance requirements set forth in the ASSE 1017 standard. Acorn Controls Command Stations are designed to reduce the potential for improper piping, missed connections and/or failing to include key system control components that are common with contractor “design-as-you-build” types of installation. Acorn Controls Command Stations have a much smaller footprint and minimize material waste on site. For any future troubleshooting that may become necessary, a Command Station ensures you have quick and easy access to all key components needed for the process.

ASSE 1017 performance based on actual demand or recirculation pump flow rate or a combination of both. See FEATURES regarding control performance at ZERO GPM user demand.
